I think what happen with my unit was it was not set up in the first place as it was a retro fit and i did not notice until the next day when I went to start up and then saw the "not configured" message. Unit has 6 disc's inserted and any one of them will eject ok when selected, so fingers crossed I got one of the good units :D Will post back if problem occurs again but like I said I think it was not configured at all in the first place.
